FAMILY I.— HYMENOMYCETES. 



OBDEB 3. — HXDIfEI. 



Symenium spread over tlie surface of spines, teeth, persistent papilla, 

 <i:c., and not lining impressed pores or tubes. 



Genus— HTDNUii, Stem central. 



HYDNUM EEPANDUM. — Xinn. 

 HEDGEHOG, OE SPINE-BEAKING MUSHROOM. 



BOTANICAL CHAEACTEES. 



Pileus : Smooth, irregular in shape, depressed in the centre more or less 

 lobeJ, and generally placed irregularly on the stem (eccentric) ; of a pale buff 

 or cinnamon colotir ; from two to five inches in diameter. Flesh firm and 

 white, when bruised it turns slightly brown. From crowded growth separate 

 lobes of the same funguses, or the pileus of different funguses often unite in 

 growth, become fused as it were, and present a single surface. 



Spines : Crowded, awl-shaped, slanting, soft and brittle, varying in size and 

 length, and of a faint cinnamon tint. 



Stem : White, short, solid, crooked, and often lateral. 



The Hedgehog Mushroom is known by many names in the different 

 Departments of France, as ^^ Eurchon" or "Urchin," " Grinace," " liiffnoclie," 

 PencMnille," " Chevrotine," " Chevrette" or " Barhe de Vache," In Tuscany it 

 is known under the name of " Steecherino, o dentino dorato." 



There is no possibility of mistaking the Hedgehog Mushroom ; when 

 once seen, it is always to be remembeted. Its awl-shaped spines crowded 

 beneath the pileus ; its size, and colour, are most marked — it resembles closely, 

 as has been said, a hghtly baked cracknel biscuit. It grows in pine or oak woods, 

 or in hedge bottoms, solitarily, in groups, or in rings. 



Hydnum repandum is certainly not a common fungus in Herefordshire. 

 It is very local, but where it does grow, in favourable seasons, there is a 

 considerable quantity of it. In Hapvood Forest it grows on the south side ; 

 and according to Mr. Stackhouse it is found ia another locality near Haugh 

 Wood J and the Eev, E. Blight found it in a hanging wood on the lull above 

 Bredwardine,
